A friend recently asked me to help him bulk up sensibly he’s skinny, eats a lot but struggles to put on weight, and wants to gain muscle without just getting soft and fat. I spent time digging into mass gainers that are actually worth trying and then put together a shortlist that covers the whole range: insane-calorie heavy hitters, mid-range serious options, and local value picks. Below I explain what each product is, what it promises on the label, how to use it, what I like and what I’d watch out for all in plain language so you can choose with context.
Quick note on strategy: mass gainers are tools to create a consistent calorie surplus. They won’t build muscle without resistance training and adequate protein across the day. Use them to add clean calories when food alone is hard to eat. Start slow, track weight and body composition, and adjust.
How I approach choosing a gainer:
- When I evaluated products for my friend, I looked for these things:
- Calories per serving (how big a surplus will it give)
- Protein per serving (muscle repair)
- Carb profile (fast vs slow carbs) and sugar content
- Any added creatine, digestive enzymes, fibre, vitamins/minerals
- Mixability, flavour, and cost per calorie/protein
- Brand trust and ingredient transparency
Now, the picks each with label highlights (I cite product pages), practical usage, pros and cons.
Optimum Nutrition Serious Mass Chocolate:
Serious Mass is marketed as a very high-calorie gainer: roughly 1,200-1,250 calories and about 50 g protein per full serving (serving size on label is large, often mixed with milk). It also contains a vitamin/mineral blend and added creatine in some formulations.
How I’d use it: Serious Mass works best as a between-meal shake when you absolutely need calories fast. For my friend I recommended starting with half a serving mixed with whole milk that’s still a large calorie load but easier on the stomach. Use it post-workout on heavy training days or as a late-night shake if you’re short on calories.
What’s good: Massive calories in one shake, useful on days when you can’t eat enough. Decent protein (50 g) helps muscle repair. Big name brand with consistent supply.
Watchouts: Full servings are huge heavy on sugars/carbs, and can cause GI upset if you’re not used to it. You’ll likely gain some fat alongside muscle if training/nutrition aren’t dialled. Also cost per kilo is high but worth it if you need a lot of calories fast.
MuscleBlaze Super Gainer XXL, Cookies & Cream:
MuscleBlaze’s Super Gainer XXL is a popular mid-tier option. One level scoop (100 g) claims around 15–22.5 g protein and ~462–560 calories per serving depending on scoop/measure and mix. The formula focuses on a mix of carbs and moderate protein for steady energy.
How I’d use it: Good for daily calorie add-ons. I told my friend to mix 1 scoop with milk post-workout or to use two smaller shakes during the day if full meals are avoided.
What’s good: More economical than the biggest international gainers; tastes decent; easier to handle portion-wise.
Watchouts: Protein per gram is lower than some heavyweights you may need to add a scoop of whey or extra dairy/eggs to hit daily protein targets. Check sugars some flavours are sweeter.
GNC Pro Performance Bulk 1340, Chocolate (extreme bulk formula):
GNC’s Bulk 1340 claims around 1,340 calories and roughly 50 g protein per serving in its large serving format positioned as an “all-in” bulking shake for those who struggle to eat. It’s high in carbs and calories specifically to force a surplus.
How I’d use it: Treat it like Serious Mass, half servings at first, build to 1 full serving if your stomach tolerates it. Ideal for ectomorphs (very lean) who need monstrous calorie intake.
What’s good: Insane calorie density, if you need to gain quickly, it gets the job done. GNC brand recognition and formulation consistency.
Watchouts: Very high carb load expect fat gain if training volume/intensity isn’t high. Also unrealistic as a daily habit for many due to volume and sugar content.
MuscleTech Mass-Tech Elite, Chocolate Fudge Cake:
MuscleTech’s Mass-Tech Elite is positioned as a performance gainer label claims vary by serving but typical messaging promises 800+ calories, a large multi-source protein amount some labels show 60–80 g depending on serving size, and added creatine (and sometimes BCAAs/enzymes). It’s more engineered for athletes.
How I’d use it: Great post-workout when paired with a solid resistance session. Because it contains creatine in the formula, you don’t need a separate creatine supplement on those days. Start with a single moderate serving and track weight gain.
What’s good: Science-forward formula (protein blend, creatine), suitable for combining with structured hypertrophy programs. Good mixability in many reviews.
Watchouts: Price is higher than basic gainers. Creatine in the blend means you must watch total creatine intake if you already supplement separately. Also check exact protein/calorie per intended serving labels and serving sizes vary.
Nutrabay Gold Bulk Up Mass Gainer, Chocolate:
Nutrabay Gold Bulk Up is an India-made gainer that claims ~30 g protein per serving, digestive enzymes (for easier digestion), and a solid calorie count per serving positioned as a cost-effective bulking option. User reviews highlight digestibility and taste.
How I’d use it: I suggested this to my friend as a sensible starter gainer it’s kinder on the wallet and often easier on the stomach because of added enzymes. Use it as an afternoon calorie boost or post-workout.
What’s good: Good balance of price, protein and added enzymes designed for day-to-day bulking without the extreme portion sizes. Local brand support and lower cost per serving.
Watchouts: If you need extreme calories for very fast gain, this won’t match the giants like Serious Mass/GNC Bulk 1340 but it’s a pragmatic long-term choice.
How to take mass gainers:
- Start with half servings for 3-7 days to test tolerance. GI upset is common if you go straight to full serving.
- Mix with milk (whole milk if you want more calories) or water (fewer calories). Milk adds protein and calories.
- Use as a between-meal shake or post-workout. Avoid replacing all meals prioritise whole foods for micronutrients.
- Track weekly weight and body composition if possible. Aim for 0.25-0.5 kg gain per week to minimise excess fat.
- Combine with a progressive resistance training program heavy compound lifts, calorie surplus and enough protein across the day are mandatory for muscle gain.
Precautions & caveats:
- If you have metabolic conditions (diabetes, fatty liver), high-calorie gainers can be risky speak to a doctor first.
- Very high protein load stresses kidneys only in pre-existing kidney disease get clearance if you have kidney issues.
- Check sugar and digestible carb sources. If you’re prone to bloating, pick formulas with digestive enzymes or start slow.
- Watch creatine content if you already use a creatine supplement, account for the total daily dose.
- Don’t use gainers as a shortcut they’re supplements, not replacements for training, sleep and nutrient-dense food.
Cost and value: The cost per kilo and per calorie varies widely. International heavyweights (ON, GNC, MuscleTech) are pricier but concentrated; Indian brands (MuscleBlaze, Nutrabay) often give better cost per serving. Buy the smallest tub first to test taste/gut tolerance before committing to large packs.

I tried Serious Mass around 2 years back and honestly I couldn’t continue beyond a week. The serving size itself felt insane, and after drinking it I just didn’t feel like eating anything for hours. Did you actually follow the full serving or did you split it? Because I feel like companies recommend unrealistic quantities.
Yeah, going full serving on Optimum Nutrition Serious Mass right away is a mistake a lot of people make. The problem isn’t just the quantity, it’s how dense it is. If you suddenly throw that many calories into your system in one go, your appetite crashes, and like you said, you don’t feel like eating anything after that. That defeats the whole purpose. What worked better for me was splitting it into smaller portions half serving, sometimes even less, and spacing it out. That way, you’re adding calories without replacing your actual meals. Mass gainers only help if they add to your intake, not replace it. If your normal eating drops because of it, you’re just shifting calories around, not increasing them.
I’m still on the fence about all this. Part of me feels like if gaining weight was this simple, everyone would just drink shakes and get bigger. There has to be some catch.
The catch is consistency and that’s where most people struggle, not the method itself. Drinking a shake is easy for a few days. Doing it consistently, while also training properly and eating enough real food, is where things start falling apart for most people. Mass gainers simplify one part of the equation calorie intake. But they don’t remove the need for discipline in other areas. You still need: regular workouts, decent sleep, consistent eating habits. Without that, even the best gainer won’t do much. So you’re right in a way, it’s not as simple as just drink and grow. But it’s also not useless. It just works as a support tool, not a shortcut.
I actually stopped using mass gainers because I felt they made me lazy with food. Like instead of fixing my diet, I was just relying on shakes. Did you ever feel that happening?
Yeah, that’s a very real downside and I have gone through that phase as well. Mass gainers can become a bit of a crutch if you let them replace actual meals. It feels convenient just mix, drink, done but over time, your overall diet quality can suffer. What worked better for me was setting a simple rule: The gainer comes after I’ve already eaten properly. That way, it acts as an addition, not a replacement. It also keeps your eating habits intact, which is important if you’re thinking long term. Your experience isn’t wrong it just depends on how you integrate it. Used properly, it helps. Used lazily, it can definitely backfire.
BigMuscles and HealthKart ones always show up when I’m browsing because they’re cheaper. Are they actually worth trying, or is it better to avoid that segment completely?
I have tried that segment out of curiosity, and I would not say it needs to be avoided completely. It really depends on what you expect from it. If the goal is simply to increase calorie intake without spending much, brands like BigMuscles and HealthKart can do the job. Where I noticed differences was in consistency and how they felt over time. Some batches tasted slightly different, mixability was not always smooth, and digestion could feel heavier compared to more premium options. That does not mean they are bad, but they are less refined. If I am on a tighter budget, I would still consider trying them, but I would pay close attention to how my body reacts. If there is regular bloating, discomfort, or you start dreading the taste, that is usually a sign to move on. For me, they work as a starting point, but not always something I stick with long-term unless everything feels comfortable.
Something I’ve always wondered : do mass gainers actually lead to clean weight gain or is it mostly fat? Because a lot of people I’ve seen using them just look bigger but not necessarily better.
That depends less on the product and more on how you are using it. Mass gainers are essentially calorie-dense. If your overall calorie intake goes way beyond what your body needs you will gain weight but not all of it will be muscle. That’s where the bulky but soft look comes from. When I used gainers the key was pairing them with proper training and not going overboard with servings. The idea is to stay in a slight calorie surplus, not an extreme one. Also protein intake and workout intensity matter just as much. The gainer supports your intake, but it doesn’t decide how your body uses those calories. That’s still driven by your training and overall diet.
MuscleBlaze gets a lot of mixed opinions online. Some people say it’s great value, others say quality isn’t consistent. From your experience, did it feel like a compromise or a solid option?
That mixed perception around MuscleBlaze is pretty real. When I used it, I didn’t feel like it was a cheap compromise in terms of results, it delivered on the basic job, which is helping you increase calorie intake without too much hassle. That’s why it’s popular. Where the difference shows up is in overall experience things like mixability, taste consistency, and how clean it feels compared to more premium options. It’s not bad, but it’s not as refined either. I would describe it as a practical choice. If budget matters, it works. If you are willing to spend more for better digestion and smoother experience, then other options might feel more comfortable long term.
I’ve always been confused between just increasing normal food vs taking a mass gainer. Like if I just eat more rice, peanut butter, bananas etc., isn’t that enough? Why even bring a supplement into it?
You can absolutely gain weight without a mass gainer and honestly, that’s always the better long-term approach.
The problem is practicality. When I was trying to gain, I realised that consistently eating enough calories every single day is harder than it sounds. You might manage it for a few days, but appetite, routine, and time all start interfering. That’s where mass gainers come in not as a replacement, but as a shortcut to bridge the gap. Drinking 500–800 calories is often easier than eating another full meal when you’re already full. But your logic is correct. If you can reliably hit your calorie needs through food alone, you don’t need a gainer. Most people just use it because it makes consistency easier, not because it’s essential.
I tried a cheaper mass gainer (don’t remember brand), and it just made me feel bloated all the time. After reading your post, I’m guessing digestion plays a bigger role than I thought. Did you notice a big difference between brands in terms of how your body reacts?
